Make Minishift cache global shared between all profiles

[gbraad]

Profile needs a shared cache solution. It is too slow to have to redownload everything every time

With the --iso-url option, you can bypass the download, by specifying an ISO from a cache which is already downloaded. If #1409 is available, this can also work for the oc client.

So, we are using ~/.minishift/cache for the global cache right?

A little late to ask, but it concerns me. Has this been decided/can it be answered ? It is a too vague and should be given before we can start on an implementation. My 2c. I can assume it would have to be... but...

I did not think it before, but we need to decide what minishift delete --clear-cache will delete (local cache per profile vs global cache). Also how the user will delete the global cache (or allinstance cache as @gbraad suggested on IRC) ?

Also does local cache make any sense now? When user is supposed to use it?
